Spalding's Wikipedia attacked after Grammy win?

Esperanza Spalding's Wikipedia page was reportedly attacked following her win at the Grammy Awards.

The jazz star picked up the trophy for 'Best New Artist' at Sunday's ceremony, beating competition from Drake, Justin Bieber, Florence & The Machine and Mumford & Sons.

Several outlets have since reported that the star's page on the online encyclopaedia was altered by people who both appeared to support and object to her win.

According to Gawker, one reported edit read: "She now has the 2011 Grammy for being the 'Best New Artist!' Even though no one has ever heard of her! Yay!"

However, the website pointed out that another reported change said: "HaHa Justin Bieber, you're just a little boy with no Grammy for 'Best New Artist'."

Spalding's page has since been locked and the offending edits removed.

Her win at the 53rd annual ceremony marked the first time that a jazz musician has picked up the 'Best New Artist' honor. She later told the Grammys YouTube telecast that she hadn't been expecting the prize, describing it as "inspiring" and "a thrill".

Bieber also spoke out following the ceremony, admitting that he was disappointed to go home empty-handed but insisting that he was "happy" for Spalding.
